after the mixing is finished, clicking 'next step', actuating a cylinder (a3, a2 are opened, and all others are closed), then, in an artery prefilling state, slowly filling by a peristaltic pump, automatically filling to a bubble sensor, manually stepping on a foot switch, completely prefilling the rest artery injection tubes, manually checking whether bubbles exist again, if not, connecting a connector to a human artery blood vessel, clamping by a tube clamp, and preventing liquid leakage:
clicking 'next step' after artery prefilling is finished, actuating a cylinder (a6, a5 are opened, and all others are closed), then, in a vein prefilling state, slowly filling by a peristaltic pump, automatically filling to a bubble sensor, manually stepping on a foot switch, completely prefilling the rest intravenous injection tubes, manually checking whether bubbles exist again, and if not, connecting a connector to a femoral vein of a human body, clamping by a tube clamp, and preventing leakage of liquid:
after clicking the next step, the air cylinder acts (a3, a2 are opened, and all the other cylinders are closed), the system is in an arterial pre-injection state at the moment, the system automatically starts arterial injection by setting a maximum injection pressure value, waits for the arterial blood vessel to be fully pre-injected, automatically stops and continuously ensures that the blood vessel is in an inflated state (through pressure detection, if the pressure is reduced, contrast medium is continuously injected), at the moment, a person leaves a CT (computed tomography) room, can start to scan the arterial blood vessel by CT, and records arterial development pictures and data, and parameters such as pressure, flow, injection time and the like can be displayed in real time during injection operation and can be stored in an SD (secure digital) card or a U disk to be used for data recording or;
after the arterial injection is finished, clicking the next step, actuating the air cylinder (a6, a5 are started, and all others are closed), wherein the air cylinder is in an intravenous pre-injection state, the system automatically starts intravenous injection by setting a maximum injection pressure value, waits for the intravenous blood vessels to be fully pre-injected, automatically stops and continuously ensures that the blood vessels are in an inflated state (through pressure detection, if the pressure is reduced, contrast medium is continuously injected), at the moment, a person leaves a CT (computed tomography) room, can start to perform CT (computed tomography) intravenous vessel scanning, and records images and data of intravenous development, and can display parameters such as pressure, flow, injection time and the like in real time during injection operation and can be stored in an SD (secure digital) card or a U disk for data recording or analysis: (intravenous injection is not needed when the cerebral artery and the coronary artery are imaged, the next step is directly clicked, and the intravenous injection step is skipped)
The application range of the invention can be further expanded, the femoral artery and the femoral vein in the groin area are placed at the end part of the injection head, and the whole body artery and the inferior vena cava are examined by radiography; firstly, injecting a contrast medium into femoral artery (the same as the above), clicking the next step after the arterial injection is finished, actuating a cylinder (a6 and a5 are started, and all the other cylinders are closed), and then, the system is in an intravenous pre-injection state, automatically starting intravenous injection by setting a maximum injection pressure value, waiting for the full pre-injection of the intravenous blood vessels, automatically stopping the system, and continuously ensuring that the blood vessels are in a filling state (through pressure detection, if the pressure is reduced, the contrast medium is continuously injected), at the moment, a person leaves a CT (computed tomography) room, can start to perform CT (computed tomography) blood vessel scanning, and records an intravenous development picture and data, and when in injection, the parameters such as pressure, flow, injection time and the like can be displayed in real time and can be stored in an SD (secure digital) card;
the system automatically stops after injection is finished, and if the 'next step' is continuously clicked, the system jumps to an 'injection finishing' page, and at the moment, the next injection process can be started through a restart button.
It is to be understood that the described embodiments are merely a few embodiments of the invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
